This one is a Wollensak 162mm f4.5 enlarging raptar that came with its own shutter. In the old days, large format enlarging lenses can be used for taking lenses, and vice versa. It has the spin wheel aperture blades, but lacks a focusing mechanism. I put the lens on a 135mm lens barrel, with the Yeenon Focus helicoid, so that I can take close up pictures. On it's own, the minimum focus distance is quite far. Let's not forget the lens hood, without which the pictures will come out hazy.
The lens is sharp but very low contrast. Not as good as my favourite Wollensak 209mm f4.5 Raptar Copy Lens, which has the traditional circular blades. The pictures come out of the Wollensak 162mm f4.5 lens is very interesting, and well worth the effort.
